Center bore measurement on 4 lug wheels?

Hello.

I'm researching wheels that will replace the beat-up set on my 1973 camper trailer. They are 13 inches and have 4 lugs on a 4 inch diameter. The wheels attach with bolts instead of nuts onto studs. I think that means they are "hub-centric." So I'm in search of a set of wheels with a center bore that measures the same or slightly larger than my hubs. A few months ago I bought a 4-on-4 wheel from a trailer supply company. It fits fine with a 64.1 mm to 67.1 mm hub ring. But I'd rather find some interesting wheels from the 70's that will fit. Does anyone know the center bore measurement on the H-Body cars?

Air-cooled VWs use lug bolts instead of nuts. 4-lug after '67 (4 x 130mm), 5-lug before '67.

I had a utility trailer with 4 on 4" wheels, and I had to enlarge the center bore of a pair of Vega wheels to fit the hubs.

I bet my trailer hubs are also too large to accommodate the Vega wheels. I might end up doing the same thing you did. Thanks for the insight

And last night on one of the Facebook H-body groups, someone needed a wheel & tire to be able to move a car around, and discovered that the spare from their trailer fit the car.
